各位同学好,请教一道题:
182.(32026-!-item-!-188;#058&006326)
C B
The organic food industry has organized a successful grassroots campaign—using Web sites, public meetings, and also mass mailings—that have convinced the Department of Agriculture to change the proposed federal regulations for organically grown food.
A. using Web sites, public meetings, and also mass mailings—that have convinced
B. using Web sites, public meetings, and mass mailings—that has convinced
C. by using Web sites, public meetings, and mass mailings—in convincing
D. by the use of Web sites, public meetings, as well as mass mailings—that convinced
E. which used Web sites, public meetings, and mass mailings—in convincing
我选的C,正确答案是B。
排除了ADE。在BC之间选,我判断by using 好于 using, 所以扔了B,选C。
请问C选项哪个地方错了,或者说哪点不如B?
多谢!
